BACKGROUND

The present disclosure relates to bromodomain proteins and compounds which modulate bromodomains, and uses therefor. Particular embodiments contemplate disease indications which are amenable to treatment by modulation of bromodomains by the compounds of the present disclosure.

SUMMARY

The present disclosure describes a select group of compounds that have demonstrated superior pharmacokinetics (PK) in comparison to compounds in earlier studies. More specifically, the compounds of Formula I and II disclosed herein are a selection invention of WO 2014/145051. The compounds of Formula I and II disclosed herein are novel compounds that are structurally unique from the specific compounds disclosed in WO 2014/145051 because the compounds in this disclosure have a di(pyridin-2-yl)methylene moiety that requires a R¹ substituent as defined in this disclosure. In contrast, the specific compounds disclosed in WO 2014/145051 that have a di(pyridin-2-yl)methylene moiety have a hydrogen at what would be the R¹ substituent as defined in this disclosure. As exemplified in this disclosure, the novel compounds described herein have demonstrated surprisingly much better PK properties compared to a structurally similar compound disclosed in WO 2014/145051, wherein the only structural difference is that the compound disclosed in WO 2014/145051 does not have the R¹ substituent as defined in this disclosure.

The present disclosure provides a compound of Formula (I):

or a pharmaceutically acceptable salt, a solvate, a tautomer, an isomer, or a deuterated analog thereof, wherein:

R¹ is cyano, halo, or (C₁-C₃)alkyl optionally substituted with 1 to 3 substituents independently selected from the group consisting of halo, methyl, ethyl, methoxy and ethoxy; and

X, when present, is halo.

Another embodiment of this disclosure relates to a pharmaceutical composition comprising the compound of Formula (I) and a pharmaceutical acceptable excipient or carrier.

Another embodiment of this disclosure relates to a pharmaceutical composition comprising the compound of Formula (I) and a pharmaceutical acceptable excipient or carrier, and another therapeutic agent.

Another embodiment relates to a method for modulating bromodomain, said method comprising: administering to a subject a compound of Formula (I) or a pharmaceutical composition comprising the compound of Formula (I) and a pharmaceutical acceptable excipient or carrier.

Another embodiment relates to a method for treating a subject suffering or at risk of a disease or condition mediated by a bromodomain, said method comprising administering to the subject in need thereof an effective amount of a compound of Formula (I) or a pharmaceutical composition comprising the compound of Formula (I) and a pharmaceutical acceptable excipient or carrier.

DETAILED DESCRIPTION I. Definitions

As used herein, the following definitions apply unless clearly indicated otherwise:

It is noted here that as used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural reference unless the context clearly dictates otherwise.

“Standard Error” as used herein is sample standard deviation divided by the square root of the sample size.

“Halogen” or “halo” means all halogens, that is, chloro (Cl), fluoro (F), bromo (Br), or iodo (I).

“Cyano” refers to the group —CN.

The term “alkyl,” by itself or as part of another substituent, means, unless otherwise stated, a straight or branched chain hydrocarbon, having the number of carbon atoms designated (i.e. C₁₋₆ means one to six carbons). Representative alkyl groups include straight and branched chain alkyl groups having 1, 2, 3, 4, 5 or 6, carbon atoms. Further representative alkyl groups include straight and branched chain alkyl groups having 1, 2 or 3 carbon atoms.

“Optional” or “Optionally” as used throughout the specification means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where the event or circumstance occurs and instances in which it does not. For example, the phrase “the aromatic group is optionally substituted with one or two alkyl substituents” means that the alkyl may but need not be present, and the description includes situations where the aromatic group is substituted with an alkyl group and situations where the aromatic group is not substituted with the alkyl group.

As used herein in connection with compounds of the present disclosure, the term “synthesizing” and like terms means chemical synthesis from one or more precursor materials.

“Protecting group” refers to a grouping of atoms that, when attached to a reactive group in a molecule, masks, reduces or prevents that reactivity. Examples of protecting groups can be found in T. W. Greene and P. G. Wuts, PROTECTIVE GROUPS IN ORGANIC CHEMISTRY, (Wiley, 4th ed. 2006), Beaucage and Iyer, Tetrahedron 48:2223-2311 (1992), and Harrison and Harrison et al., COMPENDIUM OF SYNTHETIC ORGANIC METHODS, Vols. 1-8 (John Wiley and Sons. 1971-1996). Representative amino protecting groups include formyl, acetyl, trifluoroacetyl, benzyl, benzyloxycarbonyl (CBZ), tert-butoxycarbonyl (Boc), trimethyl silyl (TMS), 2-trimethylsilyl-ethanesulfonyl (SES), trityl and substituted trityl groups, allyloxycarbonyl, 9-fluorenylmethyloxycarbonyl (FMOC), nitro-veratryloxycarbonyl (NVOC), tri-isopropylsilyl (TIPS), phenylsulphonyl and the like (see also, Boyle, A. L. (Editor), carbamates, amides, N-sulfonyl derivatives, groups of formula —C(O)OR, wherein R is, for example, methyl, ethyl, t-butyl, benzyl, phenylethyl, CH₂═CHCH₂—, and the like, groups of the formula —C(O)R′, wherein R′ is, for example, methyl, phenyl, trifluoromethyl, and the like, groups of the formula —SO₂R″, wherein R″ is, for example, tolyl, phenyl, trifluoromethyl, 2,2,5,7,8-pentamethylchroman-6-yl, 2,3,6-trimethyl-4-methoxyphenyl, and the like, and silanyl containing groups, such as 2-trimethylsilylethoxymethyl, t-butyldimethylsilyl, triisopropylsilyl, and the like, CURRENT PROTOCOLS IN NUCLEIC ACID CHEMISTRY, John Wiley and Sons, New York, Volume 1, 2000).

“Prodrug” means any compound which releases an active parent drug according to Formula (I) in vivo when such prodrug is administered to a mammalian subject. Prodrugs of a compound of Formula (I) are prepared by modifying functional groups present in the compound of Formula (I) in such a way that the modifications may be cleaved in vivo to release the parent compound. Prodrugs may be prepared by modifying functional groups present in the compounds in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent compounds. Prodrugs include compounds of Formula (I) wherein a hydroxy, amino, carboxyl or sulfhydryl group in a compound of Formula (I) is bonded to any group that may be cleaved in vivo to regenerate the free hydroxyl, amino, or sulfhydryl group, respectively. Examples of prodrugs include, but are not limited to esters (e.g., acetate, formate, and benzoate derivatives), amides, guanidines, carbamates (e.g., N,N-dimethylaminocarbonyl) of hydroxy functional groups in compounds of Formula (I), and the like. Preparation, selection, and use of prodrugs is discussed in T. Higuchi and V. Stella, “Pro-drugs as Novel Delivery Systems,” Vol. 14 of the A.C.S. Symposium Series; “Design of Prodrugs”, ed. H. Bundgaard, Elsevier, 1985; and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987, each of which are hereby incorporated by reference in their entirety.

“Tautomer” means compounds produced by the phenomenon wherein a proton of one atom of a molecule shifts to another atom. See, Jerry March, Advanced Organic Chemistry: Reactions, Mechanisms and Structures, Fourth Edition, John Wiley & Sons, pages 69-74 (1992). The tautomers also refer to one of two or more structural isomers that exist in equilibrium and are readily converted from one isomeric form to another. Examples of include keto-enol tautomers, such as acetone/propen-2-ol, imine-enamine tautomers and the like, ring-chain tautomers, such as glucose/2,3,4,5,6-pentahydroxy-hexanal and the like, the tautomeric forms of heteroaryl groups containing a —N═C(H)—NH— ring atom arrangement, such as pyrazoles, imidazoles, benzimidazoles, triazoles, and tetrazoles. Where the compound contains, for example, a keto or oxime group or an aromatic moiety, tautomeric isomerism (‘tautomerism’) can occur. The compounds described herein may have one or more tautomers and therefore include various isomers. A person of ordinary skill in the art would recognize that other tautomeric ring atom arrangements are possible. All such isomeric forms of these compounds are expressly included in the present disclosure.

“Isomers” mean compounds having identical molecular formulae but differ in the nature or sequence of bonding of their atoms or in the arrangement of their atoms in space. Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers.” “Stereoisomer” and “stereoisomers” refer to compounds that exist in different stereoisomeric forms if they possess one or more asymmetric centers or a double bond with asymmetric substitution and, therefore, can be produced as individual stereoisomers or as mixtures. Stereoisomers include enantiomers and diastereomers. Stereoisomers that are not mirror images of one another are termed “diastereomers” and those that are non-superimposable mirror images of each other are termed “enantiomers.” When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (−)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a “racemic mixture”. Unless otherwise indicated, the description is intended to include individual stereoisomers as well as mixtures. The methods for the determination of stereochemistry and the separation of stereoisomers are well-known in the art (see discussion in Chapter 4 of ADVANCED ORGANIC CHEMISTRY, 6th edition J. March, John Wiley and Sons, New York, 2007). Certain molecules claimed herein can exist in different enantiomeric and diastereomeric forms.

The compounds of the present disclosure may also contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute such compounds. For example, the compounds may be radiolabelled with radioactive isotopes, such as for example tritium (³H), iodine-125 (¹²⁵I), carbon-14 (¹⁴C), carbon-11 (¹¹C) or fluorine-18 (¹⁸F). All isotopic variations of the compounds of the present disclosure, whether radioactive or not, are intended to be encompassed within the scope of the present disclosure.

Certain molecules claimed in this patent can have one or more hydrogen atoms of the molecules replaced by one or more deuterium atoms including perdeuterated analogs, all such variants of these compounds are claimed. Further, it should be noted that the term “deuterated analog” refers to compounds where at least one hydrogen atom has been replaced by a deuterium atom. The term “deuterated” as used herein alone or as part of a group, means substituted deuterium atoms. When a particular position is designated as holding deuterium (stated as “D” or “deuterium”), it is understood that the abundance of deuterium at that position is substantially greater than the natural abundance of deuterium, which is 0.015% (i.e., at least 50.1% incorporation of deuterium).

The deuterated analog of the present disclosure may be a fully or partially deuterium substituted derivative. The deuterium substituted compound of the present disclosure can hold a fully or partially deuterium substituted alkyl, aryl or heteroaryl group. In one embodiment, the deuterium substituted compound of the present disclosure holds a fully or partially deuterium substituted alkyl group, e.g., —CD₃, CD₂CD₃, —CD₂CD₂CD₃ and the like. In another embodiment, the deuterium substituted compound of the present disclosure holds a fully or partially deuterium substituted aryl, such as phenyl, e.g., C₆D₅ or a fully or partially deuterium substituted heteroaryl, e.g., pyridyl-d₃, and the like.

The disclosure also embraces isotopically-labeled compounds of the present disclosure which are identical to those recited herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into compounds of the present disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine, and chlorine, such as, but not limited to ²H (deuterium, D), ³H (tritium), ¹¹C, ¹³C, ¹⁴C, ¹⁵N, ¹⁸F, ³¹P, ³²P, ³⁵, ³⁶Cl, and ¹²⁵I. Unless otherwise stated, when a position is designated specifically as “H” or “hydrogen,” the position is understood to have hydrogen at its natural abundance isotopic composition or its isotopes, such as deuterium (D) or tritium (3H). Certain isotopically-labeled compounds of the present disclosure (e.g., those labeled with 3H and ¹⁴C) are useful in compound and/or substrate tissue distribution assays. Tritiated (i.e., ³H) and carbon-14 (i.e., ¹⁴C) and fluorine-18 (¹⁸F) isotopes are useful for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium (i.e., ²H) may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements) and hence may be preferred in some circumstances. Isotopically labeled compounds of the present disclosure can generally be prepared by following procedures analogous to those disclosed in the Schemes and in the Examples herein below, by substituting an isotopically labeled reagent for a non-isotopically labeled reagent.

Certain compounds of the present disclosure can exist in unsolvated forms as well as solvated forms, including hydrated forms. “Hydrate” refers to a complex formed by combination of water molecules with molecules or ions of the solute. “Solvate” refers to a complex formed by combination of solvent molecules with molecules or ions of the solute. The solvent can be an organic compound, an inorganic compound, or a mixture of both. Solvate is meant to include hydrate. Some examples of solvents include, but are not limited to, methanol, N,N-dimethylformamide, tetrahydrofuran, dimethylsulfoxide, and water. In general, the solvated forms are equivalent to unsolvated forms and are encompassed within the scope of the present disclosure. Certain compounds of the present disclosure may exist in multiple crystalline or amorphous forms. In general, all physical forms are equivalent for the uses contemplated by the present disclosure and are intended to be within the scope of the present disclosure.

“Solid form” refers to a solid preparation (i.e. a preparation that is neither gas nor liquid) of a pharmaceutically active compound that is suitable for administration to an intended animal subject for therapeutic purposes. The solid form includes any complex, such as a salt, co-crystal or an amorphous complex, as well as any polymorph of the compound. The solid form may be substantially crystalline, semi-crystalline or substantially amorphous. The solid form may be administered directly or used in the preparation of a suitable composition having improved pharmaceutical properties. For example, the solid form may be used in a formulation comprising at least one pharmaceutically acceptable carrier or excipient.

The term “pharmaceutically acceptable” indicates that the indicated material does not have properties that would cause a reasonably prudent medical practitioner to avoid administration of the material to a patient, taking into consideration the disease or conditions to be treated and the respective route of administration. For example, it is commonly required that such a material be essentially sterile, e.g., for injectables.

“Pharmaceutically acceptable salt” refers to a salt which is acceptable for administration to a patient, such as a mammal (e.g., salts having acceptable mammalian safety for a given dosage regime). Such salts can be derived from pharmaceutically acceptable inorganic or organic bases and from pharmaceutically-acceptable inorganic or organic acids, depending on the particular substituents found on the compounds described herein. When compounds of the present disclosure contain relatively acidic functionalities, base addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired base, either neat or in a suitable inert solvent. Salts derived from pharmaceutically acceptable inorganic bases include aluminum, ammonium, calcium, copper, ferric, ferrous, lithium, magnesium, manganic, manganous, potassium, sodium, zinc and the like. Salts derived from pharmaceutically acceptable organic bases include salts of primary, secondary, tertiary and quaternary amines, including substituted amines, cyclic amines, naturally-occurring amines and the like, such as arginine, betaine, caffeine, choline, N, N′-dibenzylethylenediamine, diethylamine, 2-diethylaminoethanol, 2-dimethylaminoethanol, ethanolamine, ethylenediamine, N-ethylmorpholine, N-ethylpiperidine, glucamine, glucosamine, histidine, hydrabamine, isopropylamine, lysine, methylglucamine, morpholine, piperazine, piperidine, polyamine resins, procaine, purines, theobromine, triethylamine, trimethylamine, tripropylamine, tromethamine, N,N′-dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, meglumine (N-methyl-glucamine) and the like. When compounds of the present disclosure contain relatively basic functionalities, acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired acid, either neat or in a suitable inert solvent. Salts derived from pharmaceutically acceptable acids include acetic, trifluoroacetic, propionic, ascorbic, benzenesulfonic, benzoic, camphosulfonic, citric, ethanesulfonic, fumaric, glycolic, gluconic, glucoronic, glutamic, hippuric, hydrobromic, hydrochloric, isethionic, lactic, lactobionic, maleic, malic, mandelic, methanesulfonic, mucic, naphthalenesulfonic, nicotinic, nitric, pamoic, pantothenic, phosphoric, succinic, sulfuric, hydroiodic, carbonic, tartaric, p-toluenesulfonic, pyruvic, aspartic, benzoic, anthranilic, mesylic, salicylic, p-hydroxybenzoic, phenylacetic, embonic (pamoic), ethanesulfonic, benzenesulfonic, 2-hydroxyethanesulfonic, sulfanilic, stearic, cyclohexylaminosulfonic, algenic, hydroxybutyric, galactaric and galacturonic acid and the like.

Also included are salts of amino acids such as arginate and the like, and salts of organic acids like glucuronic or galactunoric acids and the like (see, for example, Berge, S. M. et al, “Pharmaceutical Salts,” J. Pharmaceutical Science, 1977, 66:1-19). Certain specific compounds of the present disclosure contain both basic and acidic functionalities that allow the compounds to be converted into either base or acid addition salts.

The neutral forms of the compounds may be regenerated by contacting the salt with a base or acid and isolating the parent compound in the conventional manner. The parent form of the compound differs from the various salt forms in certain physical properties, such as solubility in polar solvents, but otherwise the salts are equivalent to the parent form of the compound for the purposes of the present disclosure.

As used herein, the term “composition” refers to a formulation suitable for administration to an intended animal subject for therapeutic purposes that contains at least one pharmaceutically active compound and at least one pharmaceutically acceptable carrier or excipient.

“Unit dosage form” refers to a composition intended for a single administration to treat a subject suffering from a disease or medical condition. Each unit dosage form typically comprises each of the active ingredients of this disclosure plus pharmaceutically acceptable excipients. Examples of unit dosage forms are individual tablets, individual capsules, bulk powders, liquid solutions, ointments, creams, eye drops, suppositories, emulsions or suspensions. Treatment of the disease or condition may require periodic administration of unit dosage forms, for example: one unit dosage form two or more times a day, one with each meal, one every four hours or other interval, or only one per day. The expression “oral unit dosage form” indicates a unit dosage form designed to be taken orally.

In the present context, the term “therapeutically effective” or “effective amount” indicates that a compound or amount of the compound when administered is sufficient or effective to prevent, alleviate, or ameliorate one or more symptoms of a disease, disorder or medical condition being treated, and/or to prolong the survival of the subject being treated. The therapeutically effective amount will vary depending on the compound, the disease, disorder or condition and its severity and the age, weight, etc., of the mammal to be treated. In general, satisfactory results in subjects are indicated to be obtained at a daily dosage of from about 0.1 to about 10 g/kg subject body weight. In some embodiments, a daily dose ranges from about 0.10 to 10.0 mg/kg of body weight, from about 1.0 to 3.0 mg/kg of body weight, from about 3 to 10 mg/kg of body weight, from about 3 to 150 mg/kg of body weight, from about 3 to 100 mg/kg of body weight, from about 10 to 100 mg/kg of body weight, from about 10 to 150 mg/kg of body weight, or from about 150 to 1000 mg/kg of body weight. The dosage can be conveniently administered, e.g., in divided doses up to four times a day or in sustained-release form.

Bromodomains area family of (˜110 amino acid) structurally and evolutionary conserved protein interaction modules that specifically recognize acetylated lysines present in substrate proteins, notably histones. Bromodomains exist as components of large multidomain nuclear proteins that are associated with chromatin remodeling, cell signaling and transcriptional control. There are a total of 61 human bromodomains found within 46 human proteins. Examples of bromodomain-containing proteins with known functions include: (i) histone acetyltransferases (HATs), including CREBBP, GCN5, PCAF and TAFII250; (ii) methyltransferases such as ASH1L and MLL; (iii) components of chromatin-remodeling complexes such as Swi2/Snf2; and (iv) a number of transcriptional regulators (Florence et al. Front. Biosci. 2001, 6, D1008-1018).

As used herein, the terms “bromodomain mediated,” “BET-mediated,” “BRD2-mediated,” “BRD3-mediated,” “BRD4-mediated,” and/or “BRDT-mediated” disorders or conditions means any disease or other deleterious condition in which one or more of the bromodomain-containing proteins, such as BET proteins, such as BRD2, BRD3, BRD4 and/or BRDT, or a mutant thereof, are known to play a role. Accordingly, another embodiment of the present disclosure relates to treating or lessening the severity of one or more diseases in which one or more of the bromodomain-containing proteins, such as BET proteins, such as BRD2, BRD3, BRD4, and/or BRDT, or a mutant thereof, are known to play a role. For example, a disease or condition in which the biological function of bromodomain affects the development and/or course of the disease or condition, and/or in which modulation of bromodomain alters the development, course, and/or symptoms. Bromodomain mediated disease or condition includes a disease or condition for which bromodomain inhibition provides a therapeutic benefit, e.g. wherein treatment with bromodomain inhibitors, including compounds described herein, provides a therapeutic benefit to the subject suffering from or at risk of the disease or condition. The term “inhibiting bromodomain” or “bromodomain inhibitor” means a compound which inhibits the binding of a bromodomain with its cognate acetylated proteins, for example, the bromodomain inhibitor is a compound which inhibits the binding of a bromodomain to acetylated lysine residues.

In the present context, the terms “synergistically effective” or “synergistic effect” indicate that two or more compounds that are therapeutically effective, when used in combination, provide improved therapeutic effects greater than the additive effect that would be expected based on the effect of each compound used by itself.

By “assaying” is meant the creation of experimental conditions and the gathering of data regarding a particular result of the exposure to specific experimental conditions. For example, enzymes can be assayed based on their ability to act upon a detectable substrate. A compound can be assayed based on its ability to bind to a particular target molecule or molecules.

As used herein, the terms “ligand” and “modulator” are used equivalently to refer to a compound that changes (i.e., increases or decreases) the activity of a target biomolecule, e.g., an protein such as a bromodomain. Generally a ligand or modulator will be a small molecule, where “small molecule refers to a compound with a molecular weight of 1500 Daltons or less, or preferably 1000 Daltons or less, 800 Daltons or less, or 600 Daltons or less. Thus, an “improved ligand” is one that possesses better pharmacological and/or pharmacokinetic properties than a reference compound, where “better” can be defined by one skilled in the relevant art for a particular biological system or therapeutic use.

The term “binds” in connection with the interaction between a target and a potential binding compound indicates that the potential binding compound associates with the target to a statistically significant degree as compared to association with proteins generally (i.e., non-specific binding). Thus, the term “binding compound” refers to a compound that has a statistically significant association with a target molecule. Preferably a binding compound interacts with a specified target with a dissociation constant (K_(D)) of 1 mM or less, 1 μM or less, 100 nM or less, 10 nM or less, or 1 nM or less.

As used herein, the term “modulating” or “modulate” refers to an effect of altering a biological activity, especially a biological activity associated with a particular biomolecule such as a bromodomain protein. For example, an agonist or antagonist of a particular biomolecule modulates the activity of that biomolecule, e.g., an enzyme, by either increasing (e.g. agonist, activator), or decreasing (e.g. antagonist, inhibitor) the activity of the biomolecule, such as an enzyme. Such activity is typically indicated in terms of an inhibitory concentration (IC₅₀) or excitation concentration (EC₅₀) of the compound for an inhibitor or activator, respectively, with respect to, for example, an enzyme.

In the context of the use, testing, or screening of compounds that are or may be modulators, the term “contacting” means that the compound(s) are caused to be in sufficient proximity to a particular molecule, complex, cell, tissue, organism, or other specified material that potential binding interactions and/or chemical reaction between the compound and other specified material can occur.

As used herein, the term “subject” refers to a living organism that is treated with compounds as described herein, including, but not limited to, any mammal, such as a human, other primates, sports animals, animals of commercial interest such as cattle, farm animals such as horses, or pets such as dogs and cats.

The term “administering” refers to oral administration, administration as a suppository, topical contact, intravenous, intraperitoneal, intramuscular, intralesional, intranasal or subcutaneous administration, or the implantation of a slow-release device e.g., a mini-osmotic pump, to a subject. Administration is by any route, including parenteral and transmucosal (e.g., buccal, sublingual, palatal, gingival, nasal, vaginal, rectal, or transdermal). Parenteral administration includes, e.g., intravenous, intramuscular, intra-arteriole, intradermal, subcutaneous, intraperitoneal, intraventricular, and intracranial. Other modes of delivery include, but are not limited to, the use of liposomal formulations, intravenous infusion, transdermal patches, etc.

The terms “prevent,” “preventing,” “prevention” and grammatical variations thereof as used herein, refers to a method of partially or completely delaying or precluding the onset or recurrence of a disease, disorder or condition and/or one or more of its attendant symptoms or barring a subject from acquiring or reacquiring a disorder or condition or reducing a subject's risk of acquiring or reacquiring a disorder or condition or one or more of its attendant symptoms.

In connection with amino acid or nucleic sequences, the term “purified” indicates that the subject molecule constitutes a significantly greater proportion of the biomolecules in a composition than the proportion observed in a prior composition, e.g., in a cell culture. The greater proportion can be 2-fold, 5-fold, 10-fold, or more than 10-fold, with respect to the proportion found in the prior composition.

In addition, abbreviations as used herein have respective meanings as follows:

Organic Synthetic Techniques

A wide array of organic synthetic techniques exist in the art to facilitate the construction of potential modulators. Many of these organic synthetic methods are described in detail in standard reference sources utilized by those skilled in the art. One example of such a reference is March, 1994, Advanced Organic Chemistry; Reactions, Mechanisms and Structure, New York, McGraw Hill. Thus, the techniques useful to synthesize a potential modulator of bromodomain function are readily available to those skilled in the art of organic chemical synthesis.

Alternative Compound Forms or Derivatives

Compounds contemplated herein are described with reference to both generic formulae and specific compounds. In addition, compounds disclosed herein may exist in a number of different forms or derivatives, all within the scope of the present disclosure. Alternative forms or derivatives, include, for example, (a) prodrugs, and active metabolites (b) tautomers, isomers (including stereoisomers and regioisomers), and racemic mixtures (c) pharmaceutically acceptable salts and (d) solid forms, including different crystal forms, polymorphic or amorphous solids, including hydrates and solvates thereof, and other forms.

-   -   (a) Prodrugs and Metabolites

In addition to the present formulae and compounds described herein, the present disclosure also includes prodrugs (generally pharmaceutically acceptable prodrugs), active metabolic derivatives (active metabolites), and their pharmaceutically acceptable salts.

Prodrugs are compounds or pharmaceutically acceptable salts thereof which, when metabolized under physiological conditions or when converted by solvolysis, yield the desired active compound. Prodrugs include, without limitation, esters, amides, carbamates, carbonates, ureides, solvates, or hydrates of the active compound. Typically, the prodrug is inactive, or less active than the active compound, but may provide one or more advantageous handling, administration, and/or metabolic properties. For example, some prodrugs are esters of the active compound; during metabolysis, the ester group is cleaved to yield the active drug. Esters include, for example, esters of a carboxylic acid group, or S-acyl or O-acyl derivatives of thiol, alcohol, or phenol groups. In this context, a common example is an alkyl ester of a carboxylic acid. Prodrugs may also include variants wherein an —NH group of the compound has undergone acylation, such as the 1-position of the 1H-pyrrolo[2,3-b]pyridine ring, or the nitrogen of the sulfonamide group of compounds as described herein, where cleavage of the acyl group provides the free —NH group of the active drug. Some prodrugs are activated enzymatically to yield the active compound, or a compound may undergo further chemical reaction to yield the active compound. Prodrugs may proceed from prodrug form to active form in a single step or may have one or more intermediate forms which may themselves have activity or may be inactive.

As described in The Practice of Medicinal Chemistry, Ch. 31-32 (Ed. Wermuth, Academic Press, San Diego, Calif., 2001), prodrugs can be conceptually divided into two non-exclusive categories, bioprecursor prodrugs and carrier prodrugs. Generally, bioprecursor prodrugs are compounds that are inactive or have low activity compared to the corresponding active drug compound, that contain one or more protective groups and are converted to an active form by metabolism or solvolysis. Both the active drug form and any released metabolic products should have acceptably low toxicity. Typically, the formation of active drug compound involves a metabolic process or reaction that is one of the following types:

Oxidative reactions: Oxidative reactions are exemplified without limitation by reactions such as oxidation of alcohol, carbonyl, and acid functionalities, hydroxylation of aliphatic carbons, hydroxylation of alicyclic carbon atoms, oxidation of aromatic carbon atoms, oxidation of carbon-carbon double bonds, oxidation of nitrogen-containing functional groups, oxidation of silicon, phosphorus, arsenic, and sulfur, oxidative N-dealkylation, oxidative O- and S-dealkylation, oxidative deamination, as well as other oxidative reactions.

Reductive reactions: Reductive reactions are exemplified without limitation by reactions such as reduction of carbonyl functionalities, reduction of alcohol functionalities and carbon-carbon double bonds, reduction of nitrogen-containing functional groups, and other reduction reactions.

Reactions without change in the oxidation state: Reactions without change in the state of oxidation are exemplified without limitation by reactions such as hydrolysis of esters and ethers, hydrolytic cleavage of carbon-nitrogen single bonds, hydrolytic cleavage of non-aromatic heterocycles, hydration and dehydration at multiple bonds, new atomic linkages resulting from dehydration reactions, hydrolytic dehalogenation, removal of hydrogen halide molecule, and other such reactions.

Carrier prodrugs are drug compounds that contain a transport moiety, e.g., that improves uptake and/or localized delivery to a site(s) of action. Desirably for such a carrier prodrug, the linkage between the drug moiety and the transport moiety is a covalent bond, the prodrug is inactive or less active than the drug compound, the prodrug and any release transport moiety are acceptably non-toxic. For prodrugs where the transport moiety is intended to enhance uptake, typically the release of the transport moiety should be rapid. In other cases, it is desirable to utilize a moiety that provides slow release, e.g., certain polymers or other moieties, such as cyclodextrins. (See, e.g., Cheng et al., U.S. Patent Publ. No. 20040077595, applicatoin Ser. No. 10/656,838, incorporated herein by reference.) Such carrier prodrugs are often advantageous for orally administered drugs. In some instances, the transport moiety provides targeted delivery of the drug, for example the drug may be conjugated to an antibody or antibody fragment. Carrier prodrugs can, for example, be used to improve one or more of the following properties: increased lipophilicity, increased duration of pharmacological effects, increased site-specificity, decreased toxicity and adverse reactions, and/or improvement in drug formulation (e.g., stability, water solubility, suppression of an undesirable organoleptic or physiochemical property). For example, lipophilicity can be increased by esterification of hydroxyl groups with lipophilic carboxylic acids, or of carboxylic acid groups with alcohols, e.g., aliphatic alcohols. Wermuth, supra.

Metabolites, e.g., active metabolites, overlap with prodrugs as described above, e.g., bioprecursor prodrugs. Thus, such metabolites are pharmacologically active compounds or compounds that further metabolize to pharmacologically active compounds that are derivatives resulting from metabolic processes in the body of a subject. Of these, active metabolites are such pharmacologically active derivative compounds. For prodrugs, the prodrug compound is generally inactive or of lower activity than the metabolic product. For active metabolites, the parent compound may be either an active compound or may be an inactive prodrug. For example, in some compounds, one or more alkoxy groups can be metabolized to hydroxyl groups while retaining pharmacologic activity and/or carboxyl groups can be esterified, e.g., glucuronidation. In some cases, there can be more than one metabolite, where an intermediate metabolite(s) is further metabolized to provide an active metabolite. For example, in some cases a derivative compound resulting from metabolic glucuronidation may be inactive or of low activity, and can be further metabolized to provide an active metabolite.

Metabolites of a compound may be identified using routine techniques known in the art, and their activities determined using tests such as those described herein. See, e.g., Bertolini et al., 1997, J. Med. Chem., 40:2011-2016; Shan et al., 1997, J Pharm Sci 86(7):756-757; Bagshawe, 1995, Drug Dev. Res., 34:220-230; Wermuth, supra.

(b) Tautomers, Stereoisomers, and Regioisomers

It is understood that some compounds may exhibit tautomerism. In such cases, the formulae provided herein expressly depict only one of the possible tautomeric forms. It is therefore to be understood that the formulae provided herein are intended to represent any tautomeric form of the depicted compounds and are not to be limited merely to the specific tautomeric form depicted by the drawings of the formulae.

Likewise, some of the compounds according to the present disclosure may exist as stereoisomers, i.e. having the same atomic connectivity of covalently bonded atoms yet differing in the spatial orientation of the atoms. For example, compounds may be optical stereoisomers, which contain one or more chiral centers, and therefore, may exist in two or more stereoisomeric forms (e.g. enantiomers or diastereomers). Thus, such compounds may be present as single stereoisomers (i.e., essentially free of other stereoisomers), racemates, and/or mixtures of enantiomers and/or diastereomers. As another example, stereoisomers include geometric isomers, such as cis- or trans-orientation of substituents on adjacent carbons of a double bond. All such single stereoisomers, racemates and mixtures thereof are intended to be within the scope of the present disclosure. Unless specified to the contrary, all such stereoisomeric forms are included within the formulae provided herein.

In some embodiments, a chiral compound of the present disclosure is in a form that contains at least 80% of a single isomer (60% enantiomeric excess (“e.e.”) or diastereomeric excess (“d.e.”)), or at least 85% (70% e.e. or d.e.), 90% (80% e.e. or d.e.), 95% (90% e.e. or d.e.), 97.5% (95% e.e. or d.e.), or 99% (98% e.e. or d.e.). As generally understood by those skilled in the art, an optically pure compound having one chiral center is one that consists essentially of one of the two possible enantiomers (i.e., is enantiomerically pure), and an optically pure compound having more than one chiral center is one that is both diastereomerically pure and enantiomerically pure. In some embodiments, the compound is present in optically pure form, such optically pure form being prepared and/or isolated by methods known in the art (e.g. by recrystallization techniques, chiral synthetic techniques (including synthesis from optically pure starting materials), and chromatographic separation using a chiral column.

(c) Pharmaceutically Acceptable Salts

Unless specified to the contrary, specification of a compound herein includes pharmaceutically acceptable salts of such compound. Thus, compounds described herein and recited in any of the claims can be in the form of pharmaceutically acceptable salts, or can be formulated as pharmaceutically acceptable salts. Contemplated pharmaceutically acceptable salt forms include, without limitation, mono, bis, tris, tetrakis, and so on. Pharmaceutically acceptable salts are non-toxic in the amounts and concentrations at which they are administered. The preparation of such salts can facilitate the pharmacological use by altering the physical characteristics of a compound without preventing it from exerting its physiological effect. Useful alterations in physical properties include lowering the melting point to facilitate transmucosal administration and increasing the solubility to facilitate administering higher concentrations of the drug. A compound of the present disclosure may possess a sufficiently acidic, a sufficiently basic, or both functional groups, and accordingly can react with any of a number of inorganic or organic bases, and inorganic and organic acids, to form a pharmaceutically acceptable salt.

Pharmaceutically acceptable salts include acid addition salts such as those containing chloride, bromide, iodide, hydrochloride, acetate, phenylacetate, acrylate, ascorbate, aspartate, benzoate, 2-phenoxybenzoate, 2-acetoxybenzoate, dinitrobenzoate, hydroxybenzoate, methoxybenzoate, methylbenzoate, bicarbonate, butyne-1,4 dioate, hexyne-1,6-dioate, caproate, caprylate, chlorobenzoate, cinnamate, citrate, decanoate, formate, fumarate, glycolate, gluconate, glucarate, glucuronate, glucose-6-phosphate, glutamate, heptanoate, hexanoate, isethionate, isobutyrate, gamma-hydroxybutyrate, phenylbutyrate, lactate, malate, maleate, hydroxymaleate, methylmaleate, malonate, mandelate, nicotinate, nitrate, isonicotinate, octanoate, oleate, oxalate, pamoate, phosphate, monohydrogenphosphate, dihydrogenphosphate, orthophosphate, metaphosphate, pyrophosphate, 2-phosphoglycerate, 3-phosphoglycerate, phthalate, propionate, phenylpropionate, propiolate, pyruvate, quinate, salicylate, 4-aminosalicylate, sebacate, stearate, suberate, succinate, sulfate, pyrosulfate, bisulfate, sulfite, bisulfite, sulfamate, sulfonate, benzenesulfonate (i.e. besylate), ethanesulfonate (i.e. esylate), ethane-1,2-disulfonate, 2-hydroxyethanesulfonate (i.e. isethionate), methanesulfonate (i.e. mesylate), naphthalene-1-sulfonate, naphthalene-2-sulfonate (i.e. napsylate), propanesulfonate, p-toluenesulfonate (i.e. tosylate), xylenesulfonates, cyclohexylsulfamate, tartrate, and trifluoroacetate. These pharmaceutically acceptable acid addition salts can be prepared using the appropriate corresponding acid.

When acidic functional groups, such as carboxylic acid or phenol are present, pharmaceutically acceptable salts also include basic addition salts such as those containing benzathine, chloroprocaine, choline, ethanolamine, diethanolamine, triethanolamine, t-butylamine, dicyclohexylamine, ethylenediamine, N,N′-dibenzylethylenediamine, meglumine, hydroxyethylpyrrolidine, piperidine, morpholine, piperazine, procaine, aluminum, calcium, copper, iron, lithium, magnesium, manganese, potassium, sodium, zinc, ammonium, and mono-, di-, or tri-alkylamines (e.g. diethylamine), or salts derived from amino acids such as L-histidine, L-glycine, L-lysine, and L-arginine. For example, see Remington's Pharmaceutical Sciences, 19^(th) ed., Mack Publishing Co., Easton, Pa., Vol. 2, p. 1457, 1995. These pharmaceutically acceptable base addition salts can be prepared using the appropriate corresponding base.

Pharmaceutically acceptable salts can be prepared by standard techniques. For example, the free-base form of a compound can be dissolved in a suitable solvent, such as an aqueous or aqueous-alcohol solution containing the appropriate acid and then isolated by evaporating the solution. In another example, a salt can be prepared by reacting the free base and acid in an organic solvent. If the particular compound is an acid, the desired pharmaceutically acceptable salt may be prepared by any suitable method, for example, treatment of the free acid with an appropriate inorganic or organic base.

(d) Other Compound Forms

In the case of agents that are solids, it is understood by those skilled in the art that the compounds and salts may exist in different crystal or polymorphic forms, or may be formulated as co-crystals, or may be in an amorphous form, or may be any combination thereof (e.g. partially crystalline, partially amorphous, or mixtures of polymorphs) all of which are intended to be within the scope of the present disclosure and specified formulae. Whereas salts are formed by acid/base addition, i.e. a free base or free acid of the compound of interest forms an acid/base reaction with a corresponding addition base or addition acid, respectively, resulting in an ionic charge interaction, co-crystals are a new chemical species that is formed between neutral compounds, resulting in the compound and an additional molecular species in the same crystal structure.

In some instances, compounds of the present disclosure are complexed with an acid or a base, including base addition salts such as ammonium, diethylamine, ethanolamine, ethylenediamine, diethanolamine, t-butylamine, piperazine, meglumine; acid addition salts, such as acetate, acetylsalicylate, besylate, camsylate, citrate, formate, fumarate, glutarate, hydrochlorate, maleate, mesylate, nitrate, oxalate, phosphate, succinate, sulfate, tartrate, thiocyanate and tosylate; and amino acids such as alanine, arginine, asparagine, aspartic acid, cysteine, glutamine, glutamic acid, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine or valine. In combining the compound of the present disclosure with the acid or base, an amorphous complex is preferably formed rather than a crystalline material such as a typical salt or co-crystal. In some instances, the amorphous form of the complex is facilitated by additional processing, such as by spray-drying, mechanochemical methods such as roller compaction, or microwave irradiation of the parent compound mixed with the acid or base. Such methods may also include addition of ionic and/or non-ionic polymer systems, including, but not limited to, hydroxypropyl methyl cellulose acetate succinate (HPMCAS) and methacrylic acid copolymer (e.g. Eudragit® L100-55), that further stabilize the amorphous nature of the complex. Such amorphous complexes provide several advantages. For example, lowering of the melting temperature relative to the free base facilitates additional processing, such as hot melt extrusion, to further improve the biopharmaceutical properties of the compound. Also, the amorphous complex is readily friable, which provides improved compression for loading of the solid into capsule or tablet form.

Additionally, the formulae are intended to cover hydrated or solvated as well as unhydrated or unsolvated forms of the identified structures. For example, the indicated compounds include both hydrated and non-hydrated forms. Other examples of solvates include the structures in combination with a suitable solvent, such as isopropanol, ethanol, methanol, dimethyl sulfoxide, ethyl acetate, acetic acid, or ethanolamine.

Such a unit may contain, for example, 0.5 mg to 1 g, preferably 1 mg to 700 mg, more preferably 5 mg to 100 mg of a compound of the present disclosure (as a free-base, solvate (including hydrate) or salt, in any form), depending on the condition being treated, the route of administration, and the age, weight and condition of the patient. Preferred unit dosage formulations are those containing a daily dose, weekly dose, monthly dose, a sub-dose or an appropriate fraction thereof, of an active ingredient. Furthermore, such pharmaceutical formulations may be prepared by any of the methods well known in the pharmacy art.

Pharmaceutical formulations may be adapted for administration by any appropriate route, for example by the oral (including capsules, tablets, liquid-filled capsules, disintegrating tablets, immediate, delayed and controlled release tablets, oral strips, solutions, syrups, buccal and sublingual), rectal, nasal, inhalation, topical (including transdermal), vaginal or parenteral (including subcutaneous, intramuscular, intravenous or intradermal) route. Such formulations may be prepared by any method known in the art of pharmacy, for example by bringing into association the active ingredient with the carrier(s), excipient(s) or diluent. Generally, the carrier, excipient or diluent employed in the pharmaceutical formulation is “non-toxic,” meaning that it/they is/are deemed safe for consumption in the amount delivered in the pharmaceutical composition, and “inert” meaning that it/they does/do not appreciably react with or result in an undesired effect on the therapeutic activity of the active ingredient.

In some embodiments, oral administration may be used. Pharmaceutical preparations for oral use can be formulated into conventional oral dosage forms such as discreet units capsules, tablets, and liquid preparations such as syrups, elixirs, and concentrated drops. Compounds described herein may be combined with solid excipients, optionally grinding a resulting mixture, and processing the mixture of granules, after adding suitable auxiliaries, if desired, to obtain, for example, tablets, coated tablets, hard capsules, soft capsules, solutions (e.g. aqueous, alcoholic, or oily solutions) and the like. Suitable excipients are, in particular, fillers such as sugars, including lactose, glucose, sucrose, mannitol, or sorbitol; cellulose preparations, for example, corn starch, wheat starch, rice starch, potato starch, gelatin, gum tragacanth, methyl cellulose, hydroxypropylmethyl-cellulose, sodium carboxymethylcellulose (CMC), and/or polyvinylpyrrolidone (PVP: povidone); oily excipients, including vegetable and animal oils, such as sunflower oil, olive oil, or cod-liver oil.

For this purpose, concentrated sugar solutions may be used, which may optionally contain, for example, gum arabic, talc, poly-vinylpyrrolidone, carbopol gel, polyethylene glycol, and/or titanium dioxide, lacquer solutions, and suitable organic solvents or solvent mixtures. Oral fluids such as solutions, syrups and elixirs can be prepared in dosage unit form so that a given quantity contains a predetermined amount of the compound.

Pharmaceutical preparations that can be used orally include push-fit capsules made of gelatin (“gelcaps”), as well as soft, sealed capsules made of gelatin, and a plasticizer, such as glycerol or sorbitol. The push-fit capsules can contain the active ingredients in admixture with filler such as lactose, binders such as starches, and/or lubricants such as talc or magnesium stearate and, optionally, stabilizers. In soft capsules, the active compounds may be dissolved or suspended in suitable liquids, such as fatty oils, liquid paraffin, or liquid polyethylene glycols.

In some embodiments, injection (parenteral administration) may be used, e.g., intramuscular, intravenous, intraperitoneal, and/or subcutaneous. Compounds described herein for injection may be formulated in sterile liquid solutions, preferably in physiologically compatible buffers or solutions, such as saline solution, Hank's solution, or Ringer's solution. Dispersions may also be prepared in non-aqueous solutions, such as glycerol, propylene glycol, ethanol, liquid polyethylene glycols, triacetin, and vegetable oils. Solutions may also contain a preservative, such as methylparaben, propylparaben, chlorobutanol, phenol, sorbic acid, thimerosal, and the like. In addition, the compounds may be formulated in solid form, including, for example, lyophilized forms, and redissolved or suspended prior to use. The formulations may be presented in unit-dose or multi-dose containers, for example sealed ampoules and vials, and may be stored in a freeze-dried (lyophilized) condition requiring only the addition of the sterile liquid carrier, for example water for injection, immediately prior to use.

In some embodiments, transmucosal, topical or transdermal administration may be used.

Example 5: Efficacy Comparison Between Compound P-001 and Compound Z Using IPC298 Xenograft Model

Treatment: The treatments started on Day 11 after tumor inoculation when the mean tumor size reached approximately 150 mm³. Mice were randomized into 10 study groups and each group consisted of 8 mice. The test articles were administrated to the tumor-bearing mice according to predetermined treatment regimen as shown in Table 3.

TABLE 3 Treatment Schedule Dosage** Group n* Treatment (mg/kg) Route/schedule 1 10 Vehicle control — po, QD × 16 2 8 Compound P-001 10 po, QD × 16 3 8 Compound Z 10 po, QD × 16 Note: *= n equals the number of animals **= Dosing volume: adjust dosing volume based on mouse body weight (5 μL/g).

Tumor measurements and the endpoints: The major endpoint was to see if the tumor growth could be delayed or regressed. Tumor size was measured twice a week in two dimensions using a caliper, and the volume was expressed in mm³ using the formula: V=0.5 a×b² where a and b are the long and short diameters of the tumor, respectively. The tumor size was then used for calculation of tumor growth inhibition (TGI, in percent). The TGI value is an indication of antitumor effectiveness: TGI=(1−T/C)×100%. T and C are the means of relative tumor volumes of the treated and control groups, respectively. T and C are calculated using the formula: T=T_(d)/T₀×100%, C═C_(d)/C₀×100%, where T_(d) and C_(d) are tumor volumes of the treated and control animals, respectively, on Day 28 after tumor inoculation; To and Co are tumor volumes of the treated and control animals, respectively, at the start of the treatment

The tumor volumes in different groups at different time points are shown in Table 4 and Table 5 and FIG. 1. Compound P-001 alone demonstrated a strong antitumor activity with a mean tumor size of 99.2 mm³ (Table 4) and TGI=112% (Table 5) while Compound Z produced a moderate antitumor activity with the mean tumor sizes were 141.5 mm³ (Table 4) and TGI=92% (Table 5).

Thus, Compound Z produced moderate antitumor activity, while Compound P-001 demonstrated strong therapeutic efficacy. Test articles were tolerated well by the tumor-bearing animals.

Example 5: Toxicity Profile Comparison Between Compound P-001 and Compound Z

The promonocytic cell line, Ba/F3, depends on the addition of IL-3 for growth in cell culture. However Ba/F3 cells engineered to express a full length oncogene is capable of rendering Ba/F3 cells factor-independent, but become apoptotic when the oncogene or downstream signaling is inhibited by the addition of small molecule inhibitors. When injected into the tail veins of nude mice, the factor-independent Ba/F3 cells home to the spleen and proliferate to cause a marked splenomegaly. The in vivo proliferation of the factor-independent Ba/F3 cells and appearance of splenomegaly are directly dependent on the activity of the Ba/F3 cells and can be blocked by oral administration of compounds that are effective inhibitors of cell growth. Therefore, this animal model can be used to ascertain the effective doses for Ba/F3 cell inhibition, evaluation of both PK/PD effects as well as a readout of toxicity or MTD.

Table 6 provides a summary of the experimental design.

TABLE 6 DAY Ba/F3 cells scaled up in culture (six T-150's) 1 Cells washed and prepared for injections at 5 × 10⁷ cells/mL 2 Inject tail veins of 24 mice (Groups 2-7), 0.1 mL (5 × 10⁶ cells) per mouse. No injection for Group 1 (Naïve). 2-8 Wait 6 days while spleens are growing 8 Treat vehicle and Compound Z or Compound P-001 by oral gavage. Groups 2-7 QD. 15 Administer last dose and collect blood for PK analysis according to PK section below. 15 Weigh animals. Sac mice. Measure spleen and liver weights.

FIG. 2 illustrates the observed toxicity when dosing Compound P-001 and Compound Z at 10 mg/kg to nu/nu mice over a period of 7 days. Table 7 contains delta body weight changes during period of dosing.

TABLE 7 Delta Body Weight Loss Compound Day 1 Day 2 Day 3 Day 5 Day 6 Day 7 Compound Z 0 −0.125 −0.6 −1.125 −2.475 −3.75 10 mg/kg Compound P-001 0 0.75 1.375 1.125 1.825 2.075 10 mg/kg

Thus, Compound P-001 shows a significantly improved toxicity profile than Compound Z. As can be seen above, no toxicity was observed for Compound P-001 over the duration of dosing tested in this pharmacology model. Compound Z shows significant toxicity after the 2^(nd) day of dosing, and mice continue to deteriorate for remainder of study.

Example 6: Compound Properties

While the inhibitory activity of the compounds on any bromodomain and mutants thereof is important to their activity in treating of disease, the compounds described herein show favorable properties that provide advantages as a pharmaceutical as well.

The compounds described herein are useful for treating disorders related to bromodomain proteins and mutants thereof.

Alphascreen Binding Assay

Binding of compounds of Formula (I) with bromodomain 2, 3, and 4 was assessed using Alphascreen binding assay. The inhibition of the interaction between bromodomain and its acetylated target protein (Filippakopoulos P et al. 2012) was measured quantitatively using recombinant BRD proteins, an acetylated Histone 4 peptide and AlphaScreen™ technology. In absence of inhibition the BRD protein bound to AlphaScreen™ nickel chelate acceptor beads can interact with the acetylated Histone 4 peptide which is immobilized by the AlphaScreen™ Streptavidin coated beads. This interaction brings donor and acceptor beads in proximity. The close proximity allows the singlet oxygen produced by laser excitation of the donor beads to reach the acceptor beads and generate a luminescence signal. BRD inhibitors result in a decrease in the proximity signal through an inhibition of the BRD-acetylated peptide interaction.

Protein Expression and Purification

Recombinant human bromodomains containing the N-terminal bromodomain (BRD2-BD1 (71-194), BRD3-BD1 (24-144) and BRD4-BD1 (44-164)) or dual bromodomains (BRD4-BD12 (1-477), BRD4-BD12 (1-472)) were expressed in E. coli cells (in a modified pET vector) with an N-terminal six-His tag and purified using a combination of both IMAC (Ni-affinity) and size exclusion chromatography steps.

Recombinant BRD proteins were expressed using the E. coli strain BL21-CodonPlus (DE3) (Agilent Technologies CA, USA). Cells were grown in Terrific Broth (TB) media to an OD600 of 1.2 at 37° C. at which temperature was reduced to 25° C., protein was induced with 1.0 mM ispropyl-B-D-thiogalactopyranoside (“IPTG”) for 12-18 hours and harvested by centrifugation at 8000×g for 20 minutes. Cells were re-suspended in 0.1 M K₂PO₄ pH 8.0, 250 mM NaCl, 10% Glycerol, 0.75% NP-40, 25 mM Imidazole, 5 mM beta-mercaptoethanol (“BME”) with 0.2 mg/mL Lysosyme, 2.0 mM phenylmethanesulfonyl fluoride (“PMSF”), 25 μg/mL DNAse I, incubated on ice for 30 minutes and lyzed with a cell disruptor (MicroFluidics MA, USA). The lysate was clarified by centrifugation at 20,000×g for 2 hours. The protein was captured with Ni-NTA resin (Life Technologies, USA). Contaminating proteins were washed off with 25 mM Tris-HCl pH 8.3, 250 mM NaCl, 12% Glycerol and 50 mM Imidazole. Following 3× wash steps, protein was eluted step wise using a 50 mM HEPES pH 7.5, 500 mM NaCl and 400 mM Imidazole. The protein was further purified using Gel Filtration column 26/600 Superdex 200 (GE Biosciences NJ, USA) in 50 mM HEPES pH 7.5, 250 mM NaCl. The protein was aliquoted and flash-frozen in liquid Nitrogen.

Oncology Cell growth assay

Published bromodomain inhibitors JQ1 and iBET 151 have shown activity in variety of cancer cells such leukemia and lymphoma, multiple myeloma cells, NUT midline carcinoma and glioblastoma cells (Dawson M A et al. 2011; Delmore J E 2011; Chen Z et al. 2013; Filippakopoulos P et al. 2010; Mertz J A et al. 2011; Ott C J et al. 2012). In this study, we test compounds in different cancer cell lines. MV-4-11 and MOLM-13 are AML cell lines harboring a MLL-AF4 and MLL-AF9 translocation, respectively. MM.1S is a multiple myeloma cell line. SK-N-AS, IMR-32 and SK—N-BE(2) are neuroblastoma cell lines. IMR-32 and SK—N-BE(2) cell lines harbor MYCN amplifications.

MV-4-11, MM.1S, IMR-32, SK-N-AS and SK—N-BE(2) were obtained from ATCC (IL, USA) and MOLM-13 were purchased from DSMZ (Braunschweig, German). Cells are cultured as recommended by their sources. For growth inhibition studies 3000 cells are seeded in wells of a 96-well plate in 75 μL of culture media. After several hours, growth media containing compounds of Formula (I) are added to the wells. Compound at a maximal concentration of 5 mM was serially diluted 1:3 for a total of 8 point titration with DMSO as a control. A 1 μL aliquot of each dilution point is added to 249 μL growth media and 75 μL is added to each well containing cells, providing 10 μM compound at the maximum concentration point. The final concentration of DMSO in all wells is 0.2%. Cells are incubated for 72 hours, and 25 μL of CellTiter Glo Reagent (Promega GA, USA) is added to each well. Plates are shaken for approximately 10 minutes and chemiluminescent signal is read on Tecan microplate reader. The measured luminescence correlates directly with cell number.

All data is normalized to the mean of eight DMSO high control wells on each plate. A four parameter curve fit of the following formula was then applied:

Y=a+(b−a)/(1+(x/c){circumflex over ( )}d)

Where ‘a’ is the minimum, ‘b’ is the maximum, ‘c’ is the pIC50 and ‘d’ is the Hill slope. These data demonstrate that the bromodomain inhibitors tested in the above assays inhibit cell growth in oncology cell lines.

Myc Reporter Assay

In MV-4-11 cells, BRD2, BRD3 and BRD4 bind to the promoter region of MYC and regulate its transcription (Dawson M A et al. 2011). The literature bromodomain inhibitor iBET 151 could disrupt BRD4 recruitment to the MYC promoter and subsequently downregulate c-myc transcription (Dawson M A et al. 2011). Myc protein is a transcription factor that heterodimerizes with an obligatory partner Max and regulates the transcription of genes important for cell proliferation, differentiation, and apoptosis. This Myc reporter assay is used to monitor the inhibitory effect of compound of Formula (I) on Myc dependent gene expression. Effective compounds could have potential therapeutic effects in Myc-driven tumors.

The MV-4-11 Myc reporter cell line is established by infecting MV-4-11 with VSV-g pseudotyped lentivirus expressing the firefly luciferase gene under the control of a minimal (m) CMV promoter and tandem repeats of the E-box tranonriptional response element (TRE) (Qiagen IL, USA) and selecting cells in 2.5 μg/mL Puromycin.

The MV-4-11 Myc reporter cell line is maintained in Iscove's Modified Dulbecco's Medium containing 10% FBS, 1% PenStep and 2.5 μg/mL Puromycin. Cells are incubated at 37° C. in a humidified atmosphere with 5% CO₂. 25,000 cells are seeded in 96-well plate in 50 μL of culture media. After several hours, growth media containing 2× compounds are added to the wells. Compound at a maximal concentration of 5 mM is serially diluted 1:3 for a total of 8 point titration. A 1 μL aliquot of each dilution point is added to 249 μL growth media and 50 μL is added to each well containing cells, providing 10 μM compound at the maximum concentration point. DMSO treated cells serve as a high control and 10 μM JQ1 treated cells serve as a low control. Cells are incubated for a further 24 hours and 25 μL of CellTiter-Fluo Reagent (Promega GA, USA) is added to each well. Plates are shaken for approximately 2 minutes and incubated at 37° C. for 0.5 hour. Fluorescence signal is read in a Tecan Plate reader (λex=400 nm, λem=505 nm). 25 μL of One-Glo Reagent (Promega GA, USA) is then added to the plates. Chemiluminescent signal is read on Tecan plate reader. Values from the wells with no cells are subtracted from all samples for background correction. The background corrected fluorescence correlates directly with cell number, and luminescence correlates directly with Myc reporter activity.

All data is normalized to the mean of 8 high control and 4 low control wells on each plate. A four parameter curve fit of the following formula was then applied:

Y=a+(b−a)/(1+(x/c){circumflex over ( )}d)

Where ‘a’ is the minimum, ‘b’ is the maximum, ‘c’ is the pIC₅₀ and ‘d’ is the Hill slope.

It is understood that the results of these assays may vary as assay conditions are varied. Inhibition levels determined under the conditions described herein represent a relative activity for the compounds tested under the specific conditions employed. The cell based assays are likely to show variability due to the complexity of the system and the sensitivity thereof to any changes in the assay conditions. As such, some level of inhibition in the cell based assays is indicative of the compounds having some inhibitory activity for those cells, whereas lack of inhibition below the threshold of the highest concentration tested does not necessarily indicate that the compound has no inhibitory activity on the cells, only that under the conditions tested, no inhibition is observed.
